SUGGESTIONS. 181 



So long as tte ground is not covered witli snow 

 there will always be something to find on dead 

 leaves^ rotten sticks^ &c._, when there is not a green 

 leaf to be seen. But these belong to a section to 

 which we have studiously avoided all reference in 

 the foregoing pages. 



General instructions will not always apply ; but 

 in most instances^ the lowest and earliest leaves^ 

 in which vitality appears to decline_, will be most 

 likely to suffer from the attacks of fungi. This 

 rule must not be too stringently applied ; the species 

 of ^cidmm, for instance^ v/ill generally be found 

 on vigorous green leaves. 



Having found a plant infected with some rust 

 or brandy and by means of a pocket lens assured 

 yourself that it is such^ although the power is 

 insufficient to tell what it is_, collect as many leaves 

 as you are likely to require ; place them flat one 

 upon the other_, to prevent their curling up at the 

 edges_, should the weather be hot_, and yourself far 

 from home^ and lay them in your box ; or if you 

 should take in preference an old book with stiff 

 covers^ place them separately between the leaves 

 of your book^ and they will be in still better con- 

 dition^, if you desire to preserve them. Arrived at 

 home with the results of your trip^ proceed at once 

 to lay them between folds of blotting-paper^ submit 

 them to a gentle pressure^ and change tha papers 

 daily until your leaves are dry^ not forgetting to 

 keep a scrap of paper with each collection^ stating
